format - A format string for named scopes. The string can contain "%n", "%f" and "%l" placeholders for the scope name, file and line number, respectively. This parameter is mandatory.
delimiter - A string that is used to delimit the formatted scope names. Default: "->" or "<-", depending on the iteration direction.
incomplete_marker - A string that is used to indicate that the list was printed incomplete because of depth limitation. Default: "...".
empty_marker - A string that is output in case if the scope list is empty. Default: "", i.e. nothing is output.
